Benefits of technology

[0013]The present invention relates to a biliary catheter for use in biliary endoscopic procedures which incorporates rapid exchange catheter features. Rapid exchang

Problems solved by technology

The exchange of devices over a 400 cm guidewire is both time consuming and cumbersome.
The additional hands required due to the length of the guidewire results in a relatively more time consuming and costly procedure.

Embodiment Construction

[0057]FIG. 1 shows a partial elevational view of a catheter assembly 30 in accordance with the present invention. The catheter assembly 30 is used in catheter procedures for accessing targeted anatomical regions through the alimentary canal. The present invention incorporates features which allow rapid exchange of catheter by a single operator. The catheter of the present invention allows shorter length guidewires to be used, resulting in procedures which require less medical personnel, are less time consuming, and less costly. Additionally, the present invention is adaptable to most catheter devices used for catheter procedures within the alimentary canal.

[0058]Catheter assembly 30 includes a catheter 32 having a guidewire 34 passing through a portion thereof. Catheter 32 includes a shaft 36 having a proximal end 38 and a distal end 40. Operably connected to the proximal end 38 of the shaft 36 is a hub assembly 42. Hub assembly 42 couples to ancillary devices allowing access to a l...

Abstract

Catheter for use in biliary procedures, including a shaft having a proximal end and a distal end. A guidewire lumen is carried by the shaft extending from a location proximal the distal end of the shaft to a location proximate the distal end of the shaft. An opening is included for accessing the guidewire lumen from a location exterior the catheter shaft located distal the proximal end of the shaft. The guidewire lumen may be formed integral the catheter shaft. The catheter may be used in rapid exchange catheter procedures. The catheter may further include a port and channel design including a first opening into the guidewire lumen located proximal the distal end of the shaft, a second opening located proximal the first opening, and a channel extending longitudinally between the first opening and the second opening.

Description

[0001]This application is a continuation of U.S. application Ser. No. 09 / 978,430, filed Oct. 15, 2001; which is a continuation of U.S. application Ser. No. 09 / 649,351, filed Aug. 28, 2000, now U.S. Pat. No. 6,312,404; which is a divisional of U.S. application Ser. No. 09 / 257,794, filed Feb. 25, 1999, now U.S. Pat. No. 6,152,910; which is a continuation of U.S. application Ser. No. 08 / 926,390, filed Sep. 9, 1997, now U.S. Pat. No. 5,921,971; which claims the benefit of Provisional Application Ser. No. 60 / 025,235, filed Sep. 13, 1996.FIELD OF THE INVENTION[0002]The present invention relates to catheters for use in catheter procedures accessed through the alimentary canal within the human anatomy and methods of using such catheters. The catheter is particularly useful in conjunction with an endoscope for accessing the biliary tree. The present invention includes a catheter having single operator exchange or rapid exchange features which permit the use of shorter guidewires, allow less ...
